Answer:
total area = 100
Step-by-step explanation:
10 x 4 = 40
1/2 * 6 * 10 = 30 ( x 2 triangle) = 60
total area = 40 + 60
total area = 100

Answer:
Step-by-step explanation:
- The speed of the boat in the lake = x
- The speed of the current = 3 km/h
<u>Required equation:</u>
- 54 / (x + 3) + 42 / (x - 3) = 96/x
- 9x(x - 3) + 7x(x + 3) = 16(x + 3)(x - 3)
- 9x² - 27x + 7x² + 21x = 16x² - 144
- 6x = 144
- x = 144/6
- x = 24 km/h
Answer:
4(2x + 3) - x = 7x + 12
Explanation:
That's what T4L/Edge said
The final answer will be a 3x3 matrix. So you'll have 3 rows and 3 columns.
Along row one, the values are: 10, 15, 20
Along row two, the values are: 45, -5, -35
Along row three, the values are: 55, 25, -15
all of which make up the final answer. Each value in bold is the result of multiplying the outer 5 by each value inside the original matrix given. In a sense, it's like using the distributive property, though we wont be adding any of the values (everything stays separated).
